ADJUSTABLE LOCK KEEPER Filed Sept. 28, 1948 HE v Fi .2.

Inventor 3 James W. Ans/Ina Patented Oct. 23, 1951 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to new and useful improvements in locking mechanisms for doors and the like and the primary object of the present invention is to provide a longitudinally and transversely adjustable lock keeper that is so designed as to accommodate the bolt of a lock or latch which is applied to doors and thus compensate for sagging or warping of the door.

Another important object of the present invention is to provide a lock keeper including a novel and improved mounting therefor that will permit slight adjustment of the keeper in both a longitudinal and transverse direction.

A further object of the present invention is to provide an adjustable lock keeper that is extremely small and compact in structure and which is quickly and readily applied to or removed from a supporting structural element in a convenient manner.

A still further aim of the present invention is to provide a lock keeper of the aforementioned character that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which: 7

Figure 1 is an elevational view showing part of a door and a part of a frame with the present invention applied to the frame and engaging the bolt of the latch on the door;

Figure 2 is an end view looking toward the present invention;

Figure 3 is a longitudinal vertical sectional view taken substantially on the plane of section line 3-3 of Figure 1; and,

Figure 4 is a transverse horizontal sectional view taken substantially on the plane of section line 44 of Figure 2.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l represents a door or other barrier, such as a gate, window or the like and the numeral I2 indicates the frame for the door I.

A suitable lock [4 is mounted on the door in and includes a movable bolt [5 that is adapted for locking engagement with a keeper member l6 which is applied to the frame [2.

Removably secured by fasteners or the like I8? to the inner edge and outer face of the frame I2, is an angle member or anchor plate 20 the outer leg of which is provided with a longitudinal. substantially vertical slot 22 that opposes and. registers with a substantially vertical recess 24- formed in the outer face of the frame l2.

Slidably engaging the slot 22 is a substantially rectangular guide plate 26 the central portion. of which is provided with a transverse, substan-- tially rectangular projection or protuberance 28, that is slidable in a transverse recess or notch 3w formed in the inner face of the keeper l6 fortransverse substantially horizontal movement of.

the keeper I6 relative to the guide 26 and plate 20..

The reduced and flattened end portions 32 of.

the keeper I6 are provided with transverse sub-- stantially horizontal slots or openings 34 that; slidably receive fasteners 36 that are receivably' engaged in registering, internally threaded apertures 38 provided in the bearing strip or member 40 that is disposed in the recess 24 and which bears against the inner face of the plate 20.

Obviously, with the above defined structure, it will be apparent that the keeper It will be both longitudinally and transversely movable to accommodate the bolt [5 should the door l0 sag or become Warped.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. An adjustable lock keeper comprising an anchor plate having a longitudinal substantially vertical slot, means removably securing said anchor plate to a supporting structure, an elongated vertically disposed guide plate slidably received in said slot for longitudinal movement, a bearing element engaging the inner face of said anchor plate and movable with the guide plate, a keeper member having transversely slotted end portions, and fasteners extending through both the slotted end portions of said keeper member and said guide plate and threaded to said element, said fasteners connecting said guide plate to said bearing element, said guide plate being considerably wider than said fasteners and including longitudinal side edges, said fasteners extending through said guide plate medially the side edges, a substantially rectangular protuberance integrally formed with the outer face of said guide plate and contacting the outer face of said anchor plate, and a transverse recess provided in the inner face of said keeper member slidably receiving ,said protuberance for transverse sliding movement of said keeper member relative to said guide plate, 7

2. An adjustable lock keeper for an elongated supporting structural element havin arpelongated substantially vertical recess cornprising} an anchor plate having a longitudinal substantially vertical slot registering with the recess an elongated vertically disposed guide plate slidably received in said slot, an inner bearing.plate conltacting the inner face of the anchor plate and t e nne face of sai su devpla e nd, positi n d in said recess for sliding movement, a keep er m m h i g d p ri on rsaid n p r io h ving tr e sub tially ho iz ntal slot a fas n ,e i hroughv bothsaid hori- ;zontalslots and said guide plate, connecting said guide plate to said bearing plate.

,3. .An adjustable lock-keeper forla supporting said guide .plate having. a transverse substantially rectangular. projection bearing against the outer 4 face of said anchor plate, said keeper having a transverse recess slidably receiving said projection, and screws extending through both said horizontal slots and said guide plate, connecting said guide plate to said inner bearing plate, said guide plate being considerably wider than the diameter of said screws to prevent the threads of said screws from engaging the edges defining the vertical slot.

4. adjustable lock,k e,eper including an anehor platehaving a vertical slot-therein and forward and rear faces, an elongated guide plate received in said slot for vertical sliding movernentangi-including a forward face flush with the forward face of said anchor plate and a rear face flush with the rear face of said anchor plate, a horizontal plateintegrally formed with the outerraee'or said guide plate intermediate the ends of said guide plate and contacting the forward face of said anchor plate, a keeper having .upper and lower horizontal, slotsrand a recessibetween said slots} said recess slidably receiving said-horizontal plate, an elongated bearin'g plate contacting the rear faces of said guide plate and said anchor plate, and a pair of screws extending -through said upper and lower slots, theends' of said "guide plate and threaded to said bearin t c.
